Used Waymo robotaxi batteries become backup storage for power grids

Used Waymo robotaxi batteries become backup storage for power grids

Used Waymo batteries will bolster California and Texas energy storage projects.

Why this matters
Why now

The rapid growth of EV adoption is now producing a substantial volume of used batteries, coinciding with increasing demand for grid-scale energy storage to support renewable integration and grid stability.

Why it’s important

This development highlights a critical circular economy pathway for EV batteries, mitigating waste and providing a cost-effective solution for grid modernization and energy security.

What changes

The perceived lifespan and utility of EV batteries are extended, transforming them from a potential waste problem into a valuable asset for energy infrastructure.

Winners
  • · Grid operators
  • · EV battery recyclers
  • · Renewable energy developers
  • · Waymo
Losers
  • · Manufacturers of new grid-scale batteries
Second-order effects
Direct

Used EV battery repurposing accelerates, reducing demand for virgin materials in stationary storage.

Second

The economic viability of renewable energy projects improves due to cheaper and more readily available storage solutions.

Third

National energy policies increasingly incentivize and mandate second-life applications for EV batteries, creating new regulatory frameworks and industry standards.
